Facebook 图谱 API 搜索 Android

Question

我使用以下代码从 Facebook Graph API 检索数据并且它有效。

GraphRequest.newGraphPathRequest(AccessToken.getCurrentAccessToken()
                        , "/me"
                        , new GraphRequest.Callback() {
                            @Override
                            public void onCompleted(GraphResponse response) {
                                showToast(response.toString());
                                ((TextView) findViewById(R.id.result_textview)).setText(response.toString());
                            }
                        }).executeAsync();

但是，当我使用以下在 Graph API Explorer 中有效的搜索查询时，它不再有效。

GraphRequest.newGraphPathRequest(AccessToken.getCurrentAccessToken()
                        , "/search?q=coffee&type=place"
                        , new GraphRequest.Callback() {
                            @Override
                            public void onCompleted(GraphResponse response) {
                                showToast(response.toString());
                                ((TextView) findViewById(R.id.result_textview)).setText(response.toString());
                            }
                        }).executeAsync();

下面是错误json。

Response:responseCode:400,
graphObject:null,
error:{  
   HttpStatus:400,
   errorCode:100,
   errorType:GraphMethodException,
   errorMessage:   Unsupported get request. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api
}
}

请阅读文档。你做错了。

new GraphRequest(
    AccessToken.getCurrentAccessToken(),
    "...?fields={fieldname_of_type_Location}",
    null,
    HttpMethod.GET,
    new GraphRequest.Callback() {
        public void onCompleted(GraphResponse response) {
            /* handle the result */
        }
    }
).executeAsync()

或

GraphRequest request = GraphRequest.newGraphPathRequest(
  accessToken,
  "/search",
  new GraphRequest.Callback() {
    @Override
    public void onCompleted(GraphResponse response) {
      // Insert your code here
    }
});

Bundle parameters = new Bundle();
parameters.putString("type", "place");
parameters.putString("center", "53,27");
parameters.putString("distance", "30000");
request.setParameters(parameters);
request.executeAsync();

在字段中，您可以使用国家、经度、纬度、引用等。这里是 docs
